    摘要： A multilayer ceramic structure is formed by building up a plurality of layers by sequentially coating a substrate with a series of suspensions comprising particles in a fluid medium. A composition of the sequential layers are varied to produce a structure with the desired properties. The thickness of the layers can be controlled by Theological properties of the suspension and/or by the utilization of a gelling or coagulating agent. An advantage of this method is that complete drying between the subsequent coatings is not required.

    摘要： A network communication device including port control circuitry for controlling packet flow between the ports of the device, where the port control circuitry includes a port manager that directs packets between the ports and port bonding circuitry that bonds two or more of the ports into a bonded port set. For each packet to be sent via the bonded port set, the port bonding circuitry selects one of the bonded ports for transmitting the packet. More than one bonded port set may be defined in a given communication device, and each bonded port set may include from two ports up to all the ports of the device, as long as each port is included in only one bonded port set. One or more port bonding registers are provided to identify which of the plurality of ports are bonded in each bonded port set. In one embodiment, the bonded ports are selected on a packet by packet basis so as to achieve a relatively even distribution of packets sent by each bonded port. In an alternative embodiment bonded ports are assigned to packet source identifiers so as to achieve a relatively even distribution of source identifiers among the bonded ports. If bonded ports are assigned to particular source identifiers, then the traffic is preferably monitored and the assignments are periodically adjusted to achieve even distribution of packet flow on the bonded link. The bonded ports may have different bandwidths, in which case traffic is distributed on a proportionate basis.

    摘要： A network switch including a plurality of network ports for receiving and transmitting data, where each port includes at least one statistics register for storing statistics information, such as Ethernet statistical and configuration information. The switch also includes a switch manager, which further includes a memory, retrieval logic for detecting a statistics request signal and for respondingly retrieving the statistics information for storage in the memory, and response logic for asserting a statistics response signal after the statistics information is stored. A processor is coupled to the switch manager through a bus, where the processor asserts the statistics request signal and then detects assertion of the statistics response signal. Upon detecting the response signal, the processor retrieves the statistics information from the memory. In this manner, the processor is removed from direct connection to the statistics registers and free to complete other tasks while the information is being gathered by the switch manager, thereby increasing the efficiency of the processor and of the network switch. Each port preferably includes a network interface, a processor port interface for enabling the switch manager to retrieve the statistical information, and a data bus interface for network traffic. The switch manager thus includes two separate bus connections to each of the ports, so that statistical reads do not interfere with network data packet flow.

    摘要： A system for performing concurrent read and write cycles in a network switch. The network switch includes several network ports, a data bus and a switch manager to execute a concurrent read and write cycle on the data bus by asserting a first port number to identify a source port followed by a second port number to identify a destination port. Each of the ports includes a network interface for sending and receiving data packets and a data interface to store the first port number, to assert data received from the network interface onto the data bus if that port is identified by the first port number, and to retrieve data from the data bus for transmission by the network interface if that port is identified by the second port number. In this manner, data is transferred directly between a source and a destination port without being buffered in the switch manager. The bandwidth of the data bus is increased since data is transferred only once on the data bus. Latches are provided for the ports to latch the read port number to allow that write port number to be asserted during the cycle. A method of executing a concurrent read and write cycle includes the steps of asserting a first port number to identify a source port, latching the first port number, asserting a second port number to identify a destination port, and concurrently writing and reading the data on the data bus.

    摘要： A network switch including a plurality of network ports for communicating data packets, each port including logic for receiving a backpressure indication and for transmitting a jamming sequence to terminate transmission of a data packet being received. The switch includes a memory for temporarily storing data packets received by the ports, and a switch manager for determining one or more threshold conditions of the memory, for determining if a new data packet being received is to be stored in the memory for transmission by another port, and if so, for providing the backpressure indication to terminate the new data packet if a backpressure signal indicates that a threshold condition would be violated by storage of the new data packet. The jamming sequence is not sent if the packet is not intended to be stored in the switch, so that network devices coupled to a single port may continue to communicate to each other. The remaining ports of the switch are not effected. The threshold conditions include, among others, a maximum number of sectors storing data packets received by a port in a receive sector chain, a maximum number of data packets stored in the memory in a transmit packet chain, a minimum number of free sectors available in the memory for storage of data packets, and a maximum number of broadcast data packets stored in the memory.
